7b a/ZZ whom t may concern:

Be it known that I, CoRYDoN WHEAT, of Geneva, in the county of Ontario,in the State of New York, have invented new and useful` Improvements inHot-Tater and Steam Boilers, of which the following, taken in connectionwith the accompanying drawings, is a i'ull, clear, and exactdescription.

This invention relates to the class of hotwater and steam boilers in.which the watereonipartinent consists of hollow rings ari an gedhorizontally one above the other and above the ire-pot and communicatingwith each other by vertical ducts or ports between the aforesaid parts;and the invention consists in the improved construction and combinationof parts which constitute a hot-water and steain boiler oi' superiorheating capacity with `great economy in the consumption of fuel.

The invention is fully illustrated in the annexed drawings, whereinFigure l. isat'ront elevation otmy improved boiler with a portion of theinclosing-case broken away to better illustrate the forni of the boilerand its surrouinling tire-fines and heat-retaining battle-plates. Figs.2 and ."3 are horizontal transverse sections respectively on lines .e .aand l Z, Fig, i. Figs. -iand are vertical transverse sectionsrespectively on lines :i: :r and y y, Fig. 2; and Fig. (i is a detachedplan view ot' one ot' the setsV ot' water-heating rings of the boiler.

A represents the 'tire-pot, the wall of which consists ot a hollowannular shell provided with a suitableinlet, e, vfor water. Above thisfire-pot and concentric therewith are the wa* ter-h eating pipes P P P,arranged horizontally one above the other, and above said pipes isarranged the steam-deine D, said pipes beingI 'connected with each otherand with the hollow tire-pot shell A and dome I) by vertical pipes O OO, which are arranged alternately dianietrically opposite each other. lnsuch of the pipes O O which are below the water line ot' the boiler Iarrange verticalpartitions t f, which extend across the adjacent pipes PP, said partitions servi n gto divide the ascendin current ot' wateri'roin the descending current, each of said currents passing halfwayarouinl the successive pipes and causing a pert'ect circulation of thewaterin the boiler.

P P P denote annular water-heating pipes 0i' smaller circumference thanthe pipes P P P aforesaid, and arranged inside the same and concentrictherewith and communicating with the saine b v radial pipes p p. *etweenthe pipes P P, I interpose solid walls a o, preterably formed of iianges cast integral with the said pipes. Around the exterior of the pipesP P, I place a shell which is in direct contact with the exterior ofsaid pipes and forms between the same, and also around the exterior oithe fire-pot A, separate smoke-fines c c c. By the pipes P P, with theirwalls d o, a perfect con]bustion-chainber, I3, is iornied over theiire-pot A, and with this combustionchaniber the tlues c c are made tocommunicate by ports l) l) through the walls c! a at one side of thecoinbustion-chainber.

The Aflues c c are provided with ports lvl/` at points diainetricallyopposite the ports h h, as shown in 2 and 3 ot' the drawings.

C represents the inclosing-case, which forms a smoke-jacket around the'lines c, and in this sin ok e-j acket I place annular battle-plates dd. The battle-plate il rises from the base ot' the smoke jacket or caseC and extends part way the height of the saine. The bat'iieplate d isot' a greater diameter than the bathe-plate (l and suspended from thetop of the smoke-jacket, and has its lowerend terminated below the topot' the bathe-plate d, said bathe-plates sei-vin g to prevent radiationoit' heat outward Ytroni the case (l, and,by the retention of h eat inthe combustion-chambcr 'B and 'fines c c, the heating capacity ot' theboiler is greatly augmented.

In order to permit ot' cleaning the aforesaid smoke jacket or case (l, Itorni said case with a cast-iron base, C', which I provide with a door,h, and thebattle-plate (l, I mount loosely on the top ot' the ash-pit,so as to permit ot' raising the said battle-plate and allowing thesootand ashes to be scraped out troni under it and out through the door71,.

From the top of the smoke jacket crease C projects upward the exit-duef, provided with a damper, if, and from the top of thecombustion-chamber l rises an annular Aflue, y, which is extendedthrough the dome-I) and some distance above the same, and from this flueto the aforesaid line f is extended a direct exit-flue, f', providedwith a damper, n. From the top ot the iiue g is suspended the maga.-zine on, the lower portion ot' which is surrounded by the annular pipesP P P and is isolated therefrom.

IOO

In the operation of the described boiler the products of combustionascend from the firepot through the coinbustion-chamber B, and byopening the damper fn, the products of combustion escape througlithetlues g and f to the exit-[lue f. ',lhis aitords the direct draftrequired when first starting the tire. After the tire is fairly underway, the damper a is to be closed and the damper t' to be opened. Thenthe products ot' combustion will pass from the combustion-chamber Bthrough the ports l), thence circulate around through the tlues c r andpass out through the ports h into the smoke-jacket; (l, and from thenceescape to the tlue f. In ascem'ling through the combustion-chamber theproducts of combustion are caused to et't'ectually impinge the pipes P Pl and radial pipes p p p and the inner halves of the pipes P P P, and incirculating through the tlues c c c they v are brought into intin'iatecontact with the exterior of the said pipes and olf the lire-pot.

fr represents the pipe which conducts the steam or hot water to theusual radiators in the apartments to be heated.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-
